Description

Technical Field

[0001] The present invention relates to the technical field of solar energy, and specifically relates to a self - concentrating all - glass solar collector. Background Art

[0002] A solar collector is a device that converts solar radiant energy into heat energy. Due to different uses, the collector and its matching system types are divided into many kinds with different names, such as solar cookers for cooking, solar water heaters for generating hot water, solar dryers for drying items, solar furnaces for melting metals, as well as solar houses, solar thermal power stations, solar desalination devices, and so on.

[0003] For today's solar collectors, most of them use vacuum tubes as the main heat - exchange components. However, the heat - exchange tubes are mostly made of glass and are relatively fragile. For the best solar energy utilization efficiency, the heat - exchange tubes need to be exposed at the central position of the concentrator plate. This makes the heat - exchange tubes vulnerable to damage by falling objects, snow, etc. in some bad weather. Existing heat - exchange devices mostly do not have a protective structure. At the same time, due to the structural characteristics of the collector, the concentrator plate is usually an arc - shaped structure, which makes the surface of the concentrator plate easy to accumulate water stains and dust, thereby reducing the reflection effect on sunlight. Moreover, the area of the concentrator plate is usually large and it is not convenient to clean. On the other hand, according to the lighting characteristics of different regions, in order to obtain the best sunlight irradiation at different times, the orientation of the collector needs to be adjusted.

Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

The side of the mounting plate 1 is fixedly connected to the reflector 201. The reflector 201 is in an arc structure. The bottom end of the reflector 201 is fixedly connected to a bottom plate 204. A heat exchange tube 202 is installed between the mounting plate 1 and the bottom plate 204. The axis of the heat exchange tube 202 and the reflector 201 is on the same straight line. A closed arc plate 205 is rotatably connected to each side of the reflector 201. The inner side of the closed arc plate 205 is slidably connected to the reflector 201.

An operating rod 208 is rotatably connected to the middle of the mounting plate 1. A worm gear 207 is fixedly connected to the end of the driving rack 206 close to the mounting plate 1. The adjacent ends of the worm gear 207 and the operating rod 208 are meshed with each other. A heat preservation box 203 is installed on the top side of the mounting plate 1. The heat preservation box 203 is communicated with the end of the heat exchange tube 202;

[0038] The arc-shaped reflector 201 in the heat exchanger is longitudinally arranged, which can ensure the accumulation effect of sunlight, make dust and accumulated water slide down more quickly, and has a relatively small floor area. The heat exchange tube 202 is arranged at the axis position of the reflector 201 to receive the heat of sunlight most efficiently, so as to realize the heating of the water in the heat preservation box 203. In case of bad weather, in order to avoid damage to the heat exchange tube 202, the user can rotate the operating rod 208 on the side of the mounting plate 1. Through the worm gear 207, the two driving racks 206 on both sides of the reflector 201 can be driven to rotate at the same time. The driving rack 206 is meshed with the reflector 201 through the tooth groove 209. Therefore, the two closed arc plates 205 on both sides will be driven to rotate upwards at the same time until the sides of the two closed arc plates 205 are in contact, so as to completely shield the heat exchange tube 202 and avoid damage to the heat exchange tube 202 from the outside.

[0042] The water collecting trough 701 arranged on the side of the mounting plate 1 can collect and store rainwater. When the reflecting plate 201 is to be cleaned, the threaded slider 501 moves to the bottom side. At this time, the sealing plug 703 loses its support and the water delivery hole 702 is opened. At this time, the rainwater stored in the water collecting trough 701 will flow to the surface of the reflecting plate 201. With the scraping of the cleaning strip 505, the cleaning effect of the surface of the reflecting plate 201 can be improved.

[0043] Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11As shown, the stabilizing structure 6 includes a closing plate 602, the inner side of the bottom plate 204 is slidably connected with the closing plate 602, a fourth spring 606 is fixedly connected between the closing plate 602 and the bottom plate 204, the bottom end of the closing plate 602 is arranged at the drain hole 504 opened on the bottom plate 204, a protrusion-shaped structure is arranged on the top side of the closing plate 602, a connecting rod 601 is fixedly connected between the mounting plate 1 and the bottom plate 204, an arc-shaped bearing support 603 is fixedly connected to the connecting rod 601, a guide groove 605 is opened on the inner side of the bearing support 603, the bearing support 603 is slidably connected with a connecting arc plate 604 through the guide groove 605, and the connecting arc plate 604 is slidably connected to the reflecting plate 201;

[0044] When the closed arc plate 205 closes the top side of the reflecting plate 201, the connecting arc plate 604 will slide relative to the supporting support 603 and the closed arc plate 205 at the same time until the closed arc plate 205 is completely closed. At this time, the connecting arc plate 604 can support the middle position of the closed arc plate 205 to ensure stability. At the same time, a closing plate 602 is provided on the inner side of the bottom plate 204. When the closed arc plate 205 is closed, the bottom end of the closed arc plate 205 will conflict with the raised part at the top of the closing plate 602. As the closed arc plate 205 rotates, the closing plate 602 will be pushed back to the inner side of the bottom plate 204. At this time, the bottom end of the closing plate 602 can close the drain hole 504 on the bottom plate 204, so that the inner side of the reflecting plate 201 is in a relatively closed state, which provides good protection while providing a certain insulation effect for the heat exchange tube 202, especially under conditions such as cold nights.

[0045] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10As shown, the support structure 3 includes a support frame 301, the bottom side of the mounting plate 1 is rotatably connected to the support frame 301, the support frame 301 is arranged on the side of the connecting rod 601, the bottom side of the support frame 301 is rotatably connected to the base 302, the top of the base 302 is fixedly connected to a rotating block 303, the top side of the rotating block 303 is annularly provided with a plurality of grooves, the inner side of the support frame 301 is slidably connected to a first positioning block 304, the first positioning block 304 is fixedly connected to the support frame 301 with a first spring 305, the protrusion on the bottom side of the first positioning block 304 is fixedly connected to the rotating block 303 The groove conflicts with it, the side of the support frame 301 is slidably connected with a switching block 306, and a receiving groove 307 is provided on the switching block 306. The top of the first positioning block 304 is a hemispherical structure, and the top of the first positioning block 304 conflicts with the switching block 306. The two sides of the switching block 306 are respectively slidably connected with a positioning column 308, and a second spring 309 is fixedly connected between the two positioning columns 308. A plurality of positioning holes 310 are provided on the inner side of the support frame 301, and the ends of the positioning columns 308 conflict with the support frame 301 through the positioning holes 310;

[0046] Through the groove on the rotating block 303 and the convex structure on the bottom side of the first positioning block 304, the user can conveniently control the rotation angle when rotating the support frame 301. After completing the adjustment of the support frame 301, in order to fix the current rotation angle, the user can slide the switching block 306 on the side of the support frame 301 into the inside. At this time, the hemispherical structure on the top side of the first positioning block 304 will disengage from the accommodating groove 307 on the switching block 306. At this time, the first positioning block 304 directly conflicts with the switching block 306 and cannot move, thereby completing the fixing of the rotation angle. At the same time, in order to facilitate the control of the switching block 306, positioning columns 308 are respectively provided on both sides of the switching block 306, and the sliding position of the switching block 306 can be positioned through the positioning holes 310, which is convenient for use.

[0047] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, the adjusting structure 4 includes an adjusting screw 401. The adjusting screw 401 is threadedly connected to the side surface of the support frame 301. The adjusting screw 401 is arranged on the top side of the switching block 306. The end of the adjusting screw 401 is rotatably connected to a rotating head 404. A support slider 405 is rotatably connected to the rotating head 404. The side surface of the support slider 405 is slidably connected to the connecting rod 601. A chute 402 is formed on the side surface of the adjusting screw 401. A braking gear 403 is rotatably connected to the inner side of the support frame 301. The braking gear 403 is slidably connected to the adjusting screw 401 through the chute 402. A second positioning block 406 is engaged with the bottom side of the braking gear 403. A third spring 407 is fixedly connected between the second positioning block 406 and the support frame 301. The bottom end of the second positioning block 406 is in a hemispherical structure. The bottom end of the second positioning block 406 abuts against the switching block 306;

[0048] Rotate the adjusting screw 401 located on the side surface of the support frame 301. Drive the support slider 405 to slide on the connecting rod 601 through the rotating head 404 at the end of the adjusting screw 401, and the overall angle of the reflector 201 can be changed. After the adjustment is completed, since a braking gear 403 slides on the adjusting screw 401 through the chute 402, as the switching block 306 slides into the inner side of the support frame 301, the braking gear 403 will also be locked by the second positioning block 406. At this time, the attitude of the collector cannot be changed anymore, ensuring the overall stability of the device and facilitating adjustment at the same time.

[0049] When the present invention is in use, the user can rotate the operating rod 208 located on the side of the mounting plate 1, and the two driving gear rods 206 on both sides of the reflective plate 201 can be driven to rotate at the same time through the worm gear 207. The driving gear rod 206 meshes with the reflective plate 201 through the tooth groove 209, so it will eventually drive the closed arc plates 205 on both sides to rotate toward the top side at the same time until the side edges of the two closed arc plates 205 collide, thereby achieving the effect of completely shielding the heat exchange tubes 202, preventing the heat exchange tubes 202 from being damaged by the outside world. After the collector is used for a long time, the surface of the reflective plate 201 will be covered with water stains, dust, etc. These pollutants will reduce the reflective effect of the reflective plate 201 on sunlight. In order to facilitate periodic cleaning of the surface of the reflective plate 201, a 1 is provided with an arc-shaped threaded slider 501 on the inner side of the reflective plate 201. The motor 503 drives the screw rod 502 to rotate, which can drive the threaded slider 501 to slide on the inner side of the reflective plate 201, and the stains on the reflective plate 201 are scraped off by the cleaning strip 505 on the bottom side of the threaded slider 501, and the stains are discharged from the drainage hole 504 on the bottom side bottom plate 204. In order to further improve the cleaning effect of the reflective plate 201, the water collection tank 701 arranged on the side of the mounting plate 1 can collect and store rainwater. When the reflective plate 201 is cleaned, the threaded slider 501 moves to the bottom side. At this time, the sealing plug 703 loses its support and the water delivery hole 702 is connected. At this time, the rainwater stored in the water collection tank 701 will flow to the surface of the reflective plate 201, and cooperate with The scraping of the cleaning strip 505 can improve the cleaning effect on the surface of the reflective plate 201. In order to ensure that the closed arc plate 205 is stably opened and retracted, an arc-shaped supporting bracket 603 and a connecting arc plate 604 are provided on the connecting rod 601 located on the bottom side of the reflective plate 201. When the closed arc plate 205 closes the top side of the reflective plate 201, the connecting arc plate 604 will slide relative to the supporting bracket 603 and the closed arc plate 205 at the same time until the closed arc plate 205 is completely closed. At this time, the connecting arc plate 604 can support the middle position of the closed arc plate 205 to ensure stability. At the same time, a closing plate 602 is provided on the inner side of the bottom plate 204. When the closed arc plate 205 is closed, the bottom end of the closed arc plate 205 will contact the top of the closing plate 602. The raised part at the end conflicts with the raised part at the end, and with the rotation of the closed arc plate 205, the closed plate 602 will be pushed back to the inside of the bottom plate 204. At this time, the bottom end of the closed plate 602 can close the drain hole 504 on the bottom plate 204, so that the inside of the reflector 201 is in a relatively closed state, providing a good protection effect, especially providing a certain insulation effect for the heat exchange tube 202 under conditions such as cold nights. When the horizontal angle of the collector needs to be adjusted, a base 302 that rotates therewith is provided at the bottom side of the support frame 301, and a rotating block 303 is provided at the top of the base 302. Through the groove on the rotating block 303 and the convex structure on the bottom side of the first positioning block 304, the user can rotate the support frame 301.To facilitate control of the rotation angle, after completing the adjustment of the support frame 301, in order to fix the current rotation angle, the user can slide the switching block 306 on the side of the support frame 301 into the inside, and the hemispherical structure on the top side of the first positioning block 304 will be out of the receiving groove 307 on the switching block 306. At this time, the first positioning block 304 directly conflicts with the switching block 306 and cannot be moved, thereby completing the fixing of the rotation angle. At the same time, in order to facilitate the control of the switching block 306, positioning columns 308 are respectively provided on both sides of the switching block 306, and the sliding position of the switching block 306 can be positioned through the positioning holes 310, which is convenient for use. In addition to adjusting the horizontal angle of the collector, In order to obtain the best lighting angle, the user also needs to adjust the elevation angle of the collector. The user can rotate the adjustment screw 401 located on the side of the support frame 301, and drive the support slider 405 to slide on the connecting rod 601 through the rotating head 404 at the end of the adjustment screw 401, so as to change the overall angle of the reflector 201. After the adjustment is completed, since there is a brake gear 403 on the adjustment screw 401 that slides through the slide groove 402, as the switching block 306 slides into the inner side of the support frame 301, the brake gear 403 will also be locked by the second positioning block 406.
